Hi! A guy offers me his 2015 macbook pro retina 13" 8GB RAM, 256SSD with i5 cpu, for my rmbp mid-2012 15" 8GB, 256SSD. What do you guys think I should do? I want a newer macbook pro but I don't want to get rid of the performace. Also there is the logic board failure problem :/ on 2011,2012 and early 2013 models.. I work most of the time in Logic Pro X so I don't know how well does a 13" macbook pro perform. Has anybody tried? Thanks!
